It appears that starting with Java 8 Update 152 / Java 9 / Java 10, the JDK changed some of the dependencies in the packages and/or classes shipped with the JDK. So, at this time, Vault CPC 10.0.1 and earlier versions will only work with Java 7/Java 8 Update 151.

If you do not require these versions of Java, uninstall any releases, and download and install the Java 8 Update 151 JDK.

However, if you still require Java 8 Update 152 (or higher) and/or Java 9, Java 10, you can edit the vault-cpc.ini file, add the following lines BEFORE the "-data" line:

For example, the vault-cpc.ini ( found in the vault-cpc.app bundle in the ./Contents/MacOS/vault-cpc.ini, so you'll have to use a terminal or 'Show Package Contents' on the vault-cpc.app to access the file ) on a Mac is as follows:

Please note, the instructions above are for Vault Standard, but the instructions for Vault Professional are essentially the same with a couple of exceptions. Instead of vault-cpc.ini, the file name is vaultpro-cpc.ini, and the Mac OS X app bundle is named vaultpro-cpc.app.
